Vertical stripes on the TV screen

Many users encounter a common problem of vertical stripes appearing on their TV screens. This issue is typically caused by a malfunction in either the matrix, the cable, or other circuit components. When faced with this problem, users need not worry, as most of these malfunctions are not serious and can be easily fixed.

Possible causes of malfunctions

The vertical band that appears on the screen does not necessarily indicate a significant technical issue. It is possible that the cause is much simpler to fix than it initially appears. Some of the basic causes of this problem include:

1. An issue with the image settings. This can be corrected by using the automatic adjustment feature.
2. An issue with the cable connectors. Over time, the cable input may become dirty or have damaged contacts. This problem can be resolved by cleaning the connectors or soldering the pins.
3. Cable breakage. If the cable is frequently bent or broken, it can cause this problem. The solution is to replace the cable. If a replacement is not possible, using a soldering iron can be helpful, similar to the previous case.

If the band comes into view and then disappears on the plasma TV, accompanied by distortion of the image or color range, it indicates a more intricate malfunction. It becomes more challenging to rectify. Presented below are the prevailing causes behind such issues.

1. Damage or disruption of the matrix connection loop integrity.
2. Disruptions within the matrix itself.
3. Malfunction in one or more circuit components.

When it comes to completely getting rid of any malfunction, having the right desire is essential. However, for modern TV models, the cost of purchasing new components can sometimes be equivalent to buying a new device. That’s why repairing may not always be the most advisable option, especially if the TV has already served for a long time. As replacing parts doesn’t guarantee quality performance, and prolonged use can also lead to new breakdowns, it’s worth considering purchasing a new model when faced with issues.

If streaks suddenly appear on the screen and the TV hasn’t been subjected to any physical damage, taking advantage of the warranty service can be the best solution. If the warranty period hasn’t expired yet, this will be the most convenient way to deal with the situation.

In a scenario where the warranty period has expired and buying new equipment isn’t possible, there are some suggestions on how to attempt fixing the problem on your own.

Please bear in mind that it is crucial not to entrust the repair of the equipment to individuals or attempt to dismantle the device yourself while it is still under warranty. These actions may result in the termination of the warranty service and refusal of the service center to repair the device.

Loop replacement

One of the most frequent reasons for streaks appearing on the screen is cable damage.

Important notice! It is not recommended to attempt to repair intricate equipment without the necessary tools, knowledge, and expertise in this field.

Experts utilize specific machines to restore cables, but purchasing them to fix a single breakage is not cost-effective. Therefore, the best solution in this situation is to replace the cable.

To get started, it is necessary to place an order for a new component, providing the TV model and manufacturing year beforehand. In order to replace the cable, the user will require either screwdrivers or bits, depending on the model of the TV. In order to access the problematic component, the case must be disassembled with care.

Important! In certain TV models, the wires may be attached to the panel, therefore, the device body must be unscrewed and disassembled carefully, in order to avoid accidental damage.

In modern TVs, the wires are secured with special connectors, hence there is no need for desoldering when replacing the component. When the ribbon cable is detected, it should be cautiously disconnected without applying pressure on the board itself, as it can break easily.

Once you have disconnected the old cable, make sure to connect the new cable in its place. Take caution while doing so, as it is crucial to avoid damaging the contacts, which could result in a more complex and costly repair. Additionally, ensure that the new part is molded similarly to the old one in order to avoid any interference during the assembly process. Finally, reassemble the device following the reverse order of disassembly.

Please note that it is of utmost importance to refrain from bending or twisting the cable when attaching it. Such actions can cause irreparable damage to the internal contacts, rendering the part completely useless.

Matrix replacement

Issues with the matrix can be identified by a strip of a singular hue, that materializes and fades away at varying intervals. If such an issue is observed with sufficient frequency, it is prudent to contemplate rectifying it. In the event where the strip is characterized by a black shade and expands in dimension over a period of time, it signifies a malfunction with the decoder, which is nestled directly within the matrix.

• The matrix is the most expensive component in a television set, so the optimal solution to this issue would be to seek assistance from a specialized service, particularly if the warranty period has not yet expired. In case the warranty has expired, it would be advisable to contact professionals from other services. However, the user should be prepared for a significantly high price, which the technician may charge for replacing the component.

If the user decides to replace the matrix independently, there are a few important guidelines to keep in mind:

1. Most of the connections on the circuit board are delicate and highly susceptible to damage, hence the replacement of parts should be executed with utmost care.
2. For more advanced repairs, such as soldering components, specialized tools like a magnifying glass or an infrared soldering iron are imperative.
3. Repairing complex equipment without proper knowledge and skills is not recommended, as it can potentially cause more malfunctions.

Poor contact

The most evident and straightforward problem is a defective contact in the connector itself. You can easily fix this problem by simply pushing on the connection. If the contacts on the connector are oxidized, try applying more pressure. This is the most basic problem and it can be resolved quite easily. However, if the stripes on the screen persist even after performing the aforementioned actions, it is possible that the issue lies within the cable itself. In such a case, a more substantial effort will be necessary to restore it.

Vertical stripes are a relatively common issue that requires an individualized approach. Devices like LCD TVs or computer monitors are highly complex pieces of equipment that can’t be repaired by just anyone. While some problems can be resolved without any special knowledge or skills, many of the aforementioned problems may require professional assistance.
